摘要：

Multifunctional Fe3O4@TiO2 core-shell submicron particles were fabricated by a simple surface modification process that induces the magnetic submicron particles to be coated with a TiO2 shell. As characterized by field emission scanning electron microscopy, (FESEM), the as-synthesized Fe3O4@ TiO2 particles exhibit a narrow size distribution with a typical size of 248 +/- 19 nm and 8 nm in shell thickness. Magnetic measurement indicates that the as-synthesized Fe3O4@TiO2 core-shell particles are superparamagnetic at room temperature. Photocatalytic experiment is demonstrated by utilizing the oxidation reaction of 2,4,6-trichlorophenol (2,4,6-TCP) with the photofunctional magnetic nanoparticles.
